WATER-CLOSET SEAT.

SPECIFICATION forming part of Letters Patent No. 454,743, dated June 2S,1891.

Application filed March 5, 1891. Serial No. 383.825. (No model.)

To a/ZZ whom, t may concern:

Be it known that I, GERTRUDE J. KREMEL- BERG, a citizen of the UnitedStates, residing at New York, in the county and State of New York, haveinvented new and useful Improvements in Water-Closet Seats, of which theFigure l is a plan or top View when the seat isclosed. Fig. 2 is alongitudinal vertical section in the plane .r Qc, Fig. 1, when the seatis closed. Fig. 3 is a similar section when the seat is wide open. Fig.4 is a similar section when the seat has been thrown intoa position toclose by its own gravity. Fig. 5 is a sectional View of thecushioningcylinder when the seatis closed, on a larger scale than theprevious gures. Fig. 6 is a similar view of the same parts when the seatis open. Fig. 7 is an enlarged sectional View of the end of thecushioning-cylinder. Fig. 8 is a detached elevation of the rack-bar andstop which form part of the mechanism for controlling the position ofthe seat.

In the drawings, the letter A designates the floor of a water-closet.

B is the case or boX which incloses the C is the seat, and D is thecover.

On the floor is secured a hinged platform E, from which extends a leverF into the interior of the case B. This lever has its fulcrum on a pivotn, secured in the side of the case, and it connects by a rod G with theseat C. This seat is supported at its rear end by pintle or hinge jointb, and its front end rests upon a spring c, and in its normal positionthe seat occupies the position shownin Fig. 2, the cover D being closed.

On the edge of the cover is firmly secured a toothed segment H, whichengages a rackbar I. (Best seen in Figs. 5, 6, and 8.) This rack-'bar ismovably fitted into a guide or boX d, which is .firmly secured to thecase B, and when the cover D is closed the rack-bar pan.

occupies the position shown in Figs. 2 and 5; but if the cover is openedto the position shown in Fig. 3 ,and in full lines in Fig. 6 therack-bar I is pushed out to the position shown in Figs. 3, G, and 8. Ifat the same time suffi'- cient pressure is brought to bear upon theplatform E or upon the seat C, the lever F acts upon a dog c and throwsthe same into engagement with the rack-bar I, so as to pre` vent thesame from moving backward.

J is a cushioning-cylinder, the piston K of which is connected to therack-.bar I, so that when the cover D is opened to the position shown inFig. 6 the piston K is brought to bear upon a spring L, situated in theinterior of the cylinder J, so as to compress the same. At the same timeair is sucked into the cylinder through a channel f, Fig. '7, the areaof which can be regulated by a valve g.

As already stated, the dog e is held in engagement with the rack-bar Ibythe pressure brought to bear upon the seat C or upon the Yplatform E;but as soon as this pressure ceases the rack-bar is released by the doge, and the piston K (which carries the rack-bar I) is driven backward bythe spring L a sufficient distance to move the cover D from the positionshown in Fig. 3 and in full lines in Fig. 6 to the position, shown inFig. 4 and in dotted lines in Fig. 6. When the cover has reached thisposition its downward motion is checked by the air-cushion in thecylinder J,

the air-valve g being adjusted so that the air can escape from theinterior of the cylinder with more or less velocity, according to theweight of the cover. The 4dog c swings on a pivot h, which is secured inthe side of the case B, and it engages the lever E by means of apinf,\\"l1ich extends through the case, as seen in Fig. 1. From thisdescription it will be seen that the cushioning-cylinder forms a checkto prevent the cover from slamming down when the seat is relieved frompressure, said check being so constructed that its power is spent whenthe cover approaches its closing position, so that the cover ispermitted to close down snugly upon the seat.

Vhat I .claim as new, and desire to secure by Letters Patent, is*

l. The combination, with the elasticallysupported seat C and with thecover D, of the dog e, the rack-bar I, geared with the cover,

ICO

the spring- IJ, which acts upon the rack-bar when the cover is open, anda check for the descending cover, the power of which is spent as thecover approaches its closing position, substantially as described.

2. The combination, with the eiasticallysupported seat O and With thecover D, of the dog e, the' rack-bar I, geared With the cover, theeushioningcylinder J, the piston K, connected to the rack-bar I, and thespring L, Which acts upon the piston when the cover is open,substantially as described.

3. The combination, With the elastieallysupported seat C and with thecover D, of the GERTRUDE J. KREMELBERG.
